FIREWORKS=TORCH.

SPECIFICATION forming part of Letters Patent N0. 510,440, dated December12, 1893- Application filed March 15, 1893. Serial No.466,081. (Nomodel.)

To all whom it may concern:

Be it known that I, THOMAS M. PIERCE, of Concord, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Fireworks- Torches or Signal-Fuses, of which thefollowing is a full, clear, and exact description.

This invention relates to fireworks torches or signal fusees moreparticularly intended for use for railroad signal fusees, and theinvention consists of a fireworks torch or signal fusee constructed andarranged for operation all substantially as hereinafter fully describedreference being had to the accompanying sheet of drawings, in which-Figure 1 represents in side view and partial central vertical sectionthe upper end of a fireworks torch constructed in accordance with thisinvention. Fig. 2 is a cross section on line 22 Fig. 1; Fig. 3 a similarview to Fig.1 showing another form. Fig. 4 is a cross section on line 44Fig. 3.

In the drawings A represents the upper end of a casing of a fireworkstorch or signal fusee, B the fireworks composition, 0 the priming, and-D the fuse all constructed and arranged for operation as usual andneeding no more particular description herein except as relates to thepresent invention.

E is a tube or cover made of paper or of any suitable material which isadapted to freely fit over the upper end of the casing but to closelyfit an enlargement or rib F on the outer side of the casing at its upperend, which enlargement consists of a preferably narrow ring, or rim ofpaper or other suitable material secured to the casing in any suitablemanner, and having on its outer side at intervals regular, or otherwisevertical grooves, serrations or spaces H, as shown in section in Fig. 2more particularly.

In the upper end of the cover tube E is secured a plugJ of wood or ofany suitable material having a shoulder K which bears and rests againstthe upper end L of the tube or cover. The inner end of the plug ishollowed out or concave as at M, and when the cover with its plug are inplace on the upper end of the torch as shown, the end Nof the plug restsagainst and on the upper end P of the casing allowing the fuse to extendup into the space M, for the plug not to touch the same.

Generally in making the cover for the up- 7 per end of the casing it ispreferable to have it of considerable length, but if it fits closely tothe casing as it should do its full length, it is dilficult to place iton the casing on account of the confined air therein, or to remove ittherefrom on account of closeness of the fit; this invention obviatesthese difiiculties, for by enlarging the upper end of the casing a shortdistance having grooves or serrations on its outer edge, and having thecover only fit closely this enlargement, which is sufficient to securelyhold it in place, it being free of the casing below, as shown in Fig. 1,and having the corrugations or grooves or space for the escape of airwhen placing it on the fusee the cover can be easily put in place andheld securely thereon and as easily removed.

In lieu of making a special rim or rib and securing it to the case itcan be arranged as shown in Figs. 3 and 4, in which P is a paper orcloth cap, on top of the casing its edges Q bentover and secured bypaste or cement to the sides of the case and in such securing made tolap over at intervals as at R leaving between the extra thickness orlaps spaces S for the air, and the cover fitting closely the lapped overor thickened portions of the cap.

This invention provides a very simple cover for the casing that is safefrom accidental escape, in transportation, and yet can be readily put inplace and removed as is obvious. The cover can be made in any manner asdesired.

Having thus described my invention, what I claim is In a fireworks torchor signal fusee, a casing for the fireworks composition, its upper endenlarged on its outer side, said enlargement having grooves, serrationsor spaces on its outer surface, and a cover to the casing fitting saidenlargement.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

THOMAS M. PIERCE.
